Abstract
An osteotomy guide (2,102,302) is provided for cutting a bone, such as the medial distal tibia (50), for example, to facilitate an ankle replacement. The osteotomy guide (2,102,302) includes a positioning device (4,104,304) having a number of fixation points (6,8; 106, 108), a first guide member (10, 110) structured to align with a first portion (52) of the bone (50), in order to perform a first procedure on the first portion (52), and a second guide member (12,112,312) structured to align with a second portion (54) of the bone (50), in order to perform a second procedure on the second portion (54). The fixation points (6,8;106,108) engage the bone (50) and maintain alignment of the first guide member (10,110) with respect to the first portion (52) of the bone (50) during the first procedure, and maintain alignment of the second guide member (12,112,312) with respect to the second portion (54) of the bone (50) during the second procedure, in order that the first procedure and the second procedure are substantially reproducible.
Description
[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 870,223, filed December 15, 2006. technical field [0003] The present invention relates generally to the ankle joint and, more particularly, to an osteotomy guide for cutting a bone of the ankle joint, such as the inside of the distal tibia. The invention also relates to a method of cutting the medial side of the distal tibia. Background technique [0004] Access to the ankle joint is required in a variety of different situations, such as, but not limited to, talus fracture fixation, cartilage damage repair of the ankle joint, and / or joint replacement. [0005] However, access to the ankle joint is greatly limited by the anatomy surrounding the ankle joint. In particular, the lateral side of the ankle is covered by the distal fibula and relatively tough ligaments, while the anterior and posterior sides of the ankle are largely cover...
